I MPROVEMENT IN COTTON-BALE TIES.

Specification forming part of Letters Patent No. 173,118. dated February8, 1876; application filed" December 6, 1875.

4 To all whom it may concern:

Be it known that I, SAMUEL H. GILMAN, of

the city of New Orleans, in the parish of Orlongitudinal section of thetie and cotton-bale band as they appear when used together; Fig. 3, topview of tie. Fig. 4 is a diagram illustratin g the mode of producing thecam-surface; Fig. 5, a side view of the said cam and camshaft. Fig. 6 isa perspective View, showing the tie andcotton-bale bandas in use.

The nature of my invention consists in the peculiar construction andcombination of the two parts of which the tie is formed, as hereinafterdescribed and specifically claimed, whereby a very strong and simplecotton-bale tie, which is self-fastening, and always sure to bite uponthe band, is produced, and also facilities are afforded for theconstructing of the parts of the tie separately from one another, andthen uniting them together in such a manner that they can be readilyseparated in the event one of them should become inoperative. To enableothers skilled in the art to make and use my invention, I will proceedto describe the same with references to the drawlugs.

A represents a metal plate, provided upon its sides withupwardly-projecting bearingflanges A, whose distance apart'is to begoverned by the width of the bands used for the purpose of balingcotton. This plate and the flanges A are cast or made in one piece, andthe upper surface of the plate between the two flanges is madeslightlyconcave along its width, as shown at a in Fig. 2. 'I prefer toconstruct this plate about one and one-half inch in width, outsidemeasurement, from flange to flange, and about one inch in length, and ofsuch thickness as will effectually prevent any yielding when it is putin use. The

. height which the flanges A project above the upper or concave surfaceof the plate may be varied; but. 1 consider about one inch the properdistance. These flanges are provided with proper hearings to receive thejournals b of the cam-shaft B, which bearings should be so arranged asto bring the cam-shaft B horizontally above the upper surface of theplate A, and-at a sufficient distance therefrom to permit theintroduction of two thicknesses of .a hand between the cam-shaft and theplate,

as shown at D D in Figs. 2 and 6. The journal-bearing in one of theflanges A is enlarged eccentrically, as at C, Fig. 6, to correspondsomewhat with the shape of the camshaft, for the purpose of allowing thecam-shaft B tobe inserted between the flanges, while the journals of theshafts occupy their proper place in the bearin gs.

It will be observed that the metal is left out of the bearing to givethe form' as at 0, Fig.

6, below the upper point of contact between the journal and bearing, andby this means the certain (centering of the cam-shaft upon a linehorizontal to the plate, and at right angles to the vertical sides ofthe flanges, is insured, and a proper bearing for the journal,

provided, and facilities afforded for introduc ing the larger or camportion of the shaft between the flanges, which larger portion of theshaft prevents the shaft getting out of place by falling down by itsgravity below the lowest part of the aperture 0, or when the cam isgriping upon the bale-band.

The cam portion of the cam-shaft. B is of a length equal to the spacebetween the flanges A, and the curve of its periphery starts from thecircumference of the journals b of said shaft, and its distanceincreases therefromin a fixed or uniform ratio, as shown inFig. 4. ofthe drawings, or so that in every arc of ten degrees one of the radiipasses out of the camcurve at the point where a perpendicular line fromthe other intersects it. The cam-curve should pass about the shaft Buntil it meets the tangent of the radius from which it started,

as clearly shown in Fig. 4. At an angle of ten degrees or less thecontact-point of the camcurve will always jam on the band, and becarriedwith it until the space is filled; but at through the spaceremaining between the end first inserted and the cam-shaft and cam, andwhile it is drawn tight on the bale the cam of the shaft is pressedsnugly down upon the two ends of the band. This being done, and the bandset free, one end of the band slips back on the other, and by thisretraction of the band the cam-shaft is drawn partly around,

and the cam presses down upon the band with such force as to bend theends thereof, and press them down into the concave surface a of theplate A, as shown in Figs. 2 and 6 of the drawings. Thus, the tie issecurely fastened upon the band, and the two ends of the band heldfirmly together.

To unhook or unloose the tie, it is only necessary to slack the bandslightly, when the cam-shaft and cam may be turned up, and the ends ofthe band easily drawn out, leaving the tie ready to be again used for asimilar purpose. a

I am aware of the expired patent of Hughes, granted in 1859, and'do notclaim anything therein shown; but

What I claim is- 1. The cottou-bale-tie cam B, and its shaft formed withit, in combination with the flanged plate A and A A, one of the flangesof said plate having an elongated curved passage through it,substantially as and for the purpose described.

2. The combination of the flanged plate A and A A, made with a concavesurface, a, and the cam and its shaft, substantially as and for thepurpose described.

In testimony that I claim the foregoing as my invention, I hereunto setmy hand in presence of two witnesses.
